[PATCH] null dereference in fs/jbd2/journal.c
This is Eric Sesterhenn's jbd patch applied to jbd2. Commit:41716c7c21
His words: Since commitd1807793e1
we dereference a NULL pointer. Coverity id #1432. We set journal to NULL, and use it directly afterwards. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> Cc: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
